87) Hydrogen and chlorine both have two naturally occurring isotopes: 1H (1.0078 amu; 99.985 percent abudundance) and 2H (2.01410; 0.015 percent abundance), 35Cl (34.969 amu; 75.53 percent abundance) and 37Cl (36.966 amu; 24.47 percent abundance). a) How many peaks would be expected in a mass spectrum of HCl(g)? b) At what molecular weights will peaks be observed? C) What should be the relative intensities of the peaks?

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.

answer: they produce more slow than unicellular organisms.
